西安话单字音声调音强的统计分析

The Statistical Analysis on the Intensity of Xi’an Monosyllabic Tone

本文以Prrat为实验工具,运用实验语音学的方法对47位西安人的单字调音强做了统计分析。结果表明,西安话阴、上、去三声的音强曲线呈前高型,阳平音强曲线呈平台型;相对音强曲线的走势与绝对音强的基本相同,音强曲线起始处为动态段,中部为稳定段;语言背景对音强也有一定的影响作用。

Using Prrat as the tool,and based on the method of the experimental phonetics,this paper analyses the intensity of Xi’an monosyllabic tone.The results indicate that the intensity curves of first tone,third tone and the forth tone are both＂front-high＂type,while the second tone is＂flat roof＂ type.The intensity acoustic distributing of the four tones are larger at two sides,but smaller in the middle,showing that the stable segments are in the middle.
